E-Mail folders of IMAP accounts (eg Inbox or sent objects) are hidden in the "Synchronization settings", since IMAP already keeps the e-mail folders in sync (IMAP is server-based).

You can use SimpleSYN for all other local folders such as calendars, contacts, tasks, notes, etc.

If you also want to synchronize e-mail folders with SimpleSYN, then use a POP3 account on all PCs.

Close Outlook and SimpleSYN on the PC and then restart both applications.

If the behavior persists after that, check the following points:

  1. Select the right Outlook version in SimpleSYN under Options -> Advanced Options under “Outlook version”. Save the settings and restart SimpleSYN again.
  2. Make sure neither Outlook nor SimpleSYN is started with administrator rights..
  3. Check if SimpleSYN and Outlook are using the same Outlook profile. You can see the Outlook profil in SimpleSYN in the main window > Options.

No, Windows Mail is not supported by SimpleSYN. SimpleSYN supports the following versions of Outlook®:

  • Microsoft/Office 365® with Outlook® (x86/x64)
  • Outlook® 2021 (x86/x64)
  • Outlook® 2019 (x86/x64)
  • Outlook® 2016 (x86/x64)
  • Outlook® 2013 (x86/x64)

But you can use SimpleSYN Mobile to synchronize Outlook® with Windows Mail.

Category: Operation, Version 5.x, Version 6.x

When using the automatic synchronization it is also possible to synchronize all Outlook® subfolders automatically. The Outlook® subfolders will use the same synchronization direction and settings as their parent folder. Changes to the folder hierarchy below a selected folder are being synchronized.

Changes of the selected parent folder are not automatically synchronized. If a selected parent folder is being moved or deleted, the synchronization of this folder and all of its children will stop and is marked with a red X in the synchronization settings.

If you would like to continue synchronizing this folder at the new location, check the assignment of the folder in the synchronization settings on the client PC and save the page.

Moved subfolders are being deleted and completely resynchronized on the remote computer Deleted folders are also deleted on the remote side; all data inside the folder will be deleted in this case.

No, the trial version has no restrictions whatsoever; you have access to the full potential of SimpleSYN. There is merely a dialog window on startup informing you how many days you have left on the test version, which you have to manually confirm.  You can use and test SimpleSYN for 30 days, for free and noncommittal. After the trial period has ended SimpleSYN cannot be started.

The message "destination folder was not found" appears if the top folder level in Outlook (eg "Personal folders") has been named differently on the SimpleSYN client and SimpleSYN server. In this case, SimpleSYN can not assign the destination folders automatically because no new PST files are created by SimpleSYN.

Click on the "Select a different target folder" link and select the folder where you want to sync.

Alternatively, you can name the highest folder level identically on all computers in advance.

Duplicate e-mails can occur on an POP3 account, when e-mails from more than one computer being synchronized are requested from the e-mail server. This is the case if the Outlook function “Leave copy of messages on the server” was activated in a POP3 E-mail account.

The tricky here is that SimpleSYN cannot force Outlook to stop downloading an email a second time on another computer. If the first computer downloads the mail from the email server and it gets synchronized before the second computer downloads it, Outlook cannot detect that the email is already there. The second computer will than download the email from the email server and you got a duplicate. As the first email is also already synchronized, SimpleSYN assumes that the second download is intentional and synchronizes this copy too.

In this case deactivate the Outlook function “Leave copy of messages on the server” so as not to save e-mails in your mail server and download them repeatedly.

To deactivate this function follow these steps:

  1. Open Outlook
  2. Open the Backstage area by clicking on “File“
  3. In the category “Information” click on “Account Settings” and “Add or Remove Accounts…”
  4. Highlight the POP3 E-mail account in question and click on “Change“
  5. Click on “More Settings“
  6. In the tab “Advanced” deactivate the check box “Leave copy of messages on the server“
  7. Confirm the changes by clicking “OK“
  8. Click on “Next“ and then on “Finish“

SimpleSYN Standard is fully compatible with the Business Version. You can only synchronize over a local network with the standard version, however.

Please note: The SimpleSYN server has to be in the same local network as the client.

Please note:

  • The Windows service is only available in the SimpleSYN business version. In the SimpleSYN standard version, a Windows user must be logged in to the computer for synchronization
  • You cannot synchronize your Google calendar or iCloud data with SimpleSYN

SimpleSYN requires an active internet connection for its operation. The internet connection is required to connect to a central server operated by SimpleSYN. This server is used to help in the establishment of a direct connection between the SimpleSYN server and SimpleSYN client. Only data required for establishing the connection is transferred via this central server. After establishing an connection, SimpleSYN uses the best connectivity available.

In either case the connection between SimpleSYN will always  use an SSL/TLS encryption respectively. Your Outlook data is never transferred in clear-text nor stored permanently on our Internet servers (no Cloud).

As Internet flat rates are more and more common nowadays, we have decided to use the same connection technique for the standard version. The only difference is, that the standard version will only establish a connection in the local network.

If you would like to use SimpleSYN without an internet connection or without our central server, then there is the option of changing the connection configuration so that our central server is no longer necessary.

Please note:

If you are using the SimpleSYN business version, the synchronization will only work in the same local network after the changeover, but no longer between separate networks via the Internet. The option is therefore more suitable for the SimpleSYN standard version if you do not want our central server to be used.

You can activate the “Custom connection mode“ for SimpleSYN starting from version 5 as follows:

For this open the SimpleSYN main window> Options> Advanced Options.

Activate the option "Custom connection mode" on all PCs (server and clients).

On your clients enter in the filed “Custom server name / address” the computer name or static IP address from your SimpleSYN server.

The behavior can occur if Outlook was installed in a different bit version than the previous version during the new installation. In this case, the bit versions of Outlook and SimpleSYN no longer match and SimpleSYN can no longer be started.

Uninstall SimpleSYN under the Windows control panel (or under "Apps") and then reinstall SimpleSYN.

If the behavior occurs again afterwards, then install SimpleSYN in the correct bit version as follows:

  1. First find out in which bit version (32 bit or 64 bit) Outlook was installed after the reinstallation. To do this, open Outlook and click on "File > Office Account > About Outlook". You can see the bit version behind the version number.
  2. Uninstall SimpleSYN from the Windows control panel  (or under "Apps").
  3. Then download SimpleSYN and navigate to the directory where the "SimpleSYN.exe" file (for the standard version) or "SimpleSYN_Business.exe" file (for the business version) is located (e.g. on the desktop or in the download folder) .
  4. In this directory, press and hold the „shift" key on the keyboard and right click in a free area and select " Open PowerShell window here " from the context menu.

  5. After that, the Windows PowerShell window will open.

    Now type in the following command and press the ENTER key (Note: Pay attention to the correct spelling. There is no space at the beginning of the command between ".\").

    With the standard version:

    When you have installed Outlook in 32-Bit, use the following command:
    .\SimpleSYN.exe Platform=x86

    When you have installed Outlook in 64-Bit, use the following command:
    .\SimpleSYN.exe Platform=x64

    With the business version:

    When you have installed Outlook in 32-Bit, use the following command:
    .\SimpleSYN_business.exe Platform=x86

    When you have installed Outlook in 64-Bit, use the following command:
    .\SimpleSYN_business.exe Platform=x64

  6. You can then install SimpleSYN. After the installation, SimpleSYN is started correctly again.
